Raspberry Pi is one of the best-selling, general-purpose computers in the world. When it was made available to the public in February 2012, the original sales target was just 10,000 units. On launch day, more than 100,000 units sold, and over the course of one year, that total would grow to 1 million.
在不到十年的时间,因为它首次亮相,3000万iterations of the Raspberry Pi have been sold worldwide. So how did a minimalist single-board computer (SBC) built to inspire more young people to study computer science become such a staple of electronics design? Like any good story, it starts with humble beginnings.
谦虚（pi）开头
Eben Upton知道，计算机对于学校来说太昂贵了，并且直接看到了这对对计算机科学感兴趣的大学生的影响。他注意到参加相关课程的学生越来越少。在那些参加注册的学生中，他们缺乏成功的基本编程技能。他想提供一个负担得起的选择，可以帮助任何人，每个人都可以访问编码和计算机科学。
Upton’s second prototype, which was created in 2008, would be the one to give the single-board computer its well-known name. This machine, though not the powerful Pi most people recognize, had a blinking cursor that would boot into any Python code; thus, explaining the use of the word “Pi.”
至于“覆盆子”，厄普顿紧随其后的其他计算机和技术设备公司的果味步骤：橘子计算机系统，杏计算机，苹果计算机和1978年成立的英国公司，Acorn Computers，这是（有趣的事实）橡树的果实。
In 2009, the Raspberry Pi Foundation, which works to put the power of computing and digital making into the hands of people all over the world, was formed. The Foundation created the hardware, software, and educational outreach for what would eventually become the Raspberry Pi.
In 2011, the BBC showed a tiny prototype with an onboard camera and inline USB format(see figure)。这种USB加密狗风格的设备从未上市，但是在Raspberry Pi Zero中肯定会感觉到它的精神。
然后，Raspberry Pi移至片上的Broadcom系统（BCM2835）。该Broadcom芯片组最终将移动以用于Raspberry Pi型A，B，B+，Compute模块和Raspberry Pi Zero中。Alpha董事会开始以许多核心为特色Raspberry Pi特征：
- HDMI出去
- 类似物video
- USB端口
- SD card
在2011年底至2012年初之间，Eben和他的团队最终确定了最初的Raspberry Pi板的Beta版本。最初的设计包括两个USB 2.0端口，100-mb/s以太网和现在著名的26针GPIO标头。发射处理器是一个700 MHz的单核处理器和视频IV GPU，能够使用硬件加速1080p视频播放。
正是Raspberry Pi 1 M型B在2012年2月推出后的第一天就达到了100,000个销售。这是第一个Raspberry Pi的成功的一部分来自与纽瓦克的合作伙伴关系。通过减少交货时间，提高灵活性并确保零件供应的可用性和可靠性，在大规模生产后的两年内销售了超过200万个单位。
Finger in Every Pi
Raspberry Pi现在掌握在成千上万的老师，学生，制造商和专业人士的手中，他们继续发现实用和非常规的用途。
The versatile SBC has acquired a laundry list of uses over the years, including an arcade game, a baby monitor, and a weather station. It can even power amusic and light show that went viraland was shared as anextended promotional videoon ABC’s “The Great Christmas Light Fight.”
Forums and chatrooms dedicated to all things Pi—new ways of using it, Questions & Answers, project highlights, and more—popped up all over the internet. One of those online communities,元素14, celebrated Pi day this year with a roundup of their favorite Raspberry Pi projects. These grassroots inventions included everything from a speech-to-text light-up face mask to help the hard of hearing, to an International Space Station tracker for interstellar enthusiasts.
But Raspberry Pi doesn’t just live online or in the hands of tech and robotics hobbyists. In 2014, when the Compute Module was introduced, professional designers and makers were able to incorporate the SBC into their own custom systems and form factors. This flung the Raspberry Pi into a whole new marketplace.
2021年，该公司推出了$ 4 Raspberry Pi Pico，这是一种低成本的微控制器设备，可用于控制和接收各种电子设备的输入。PICO适用于微控制器，原始Raspberry Pi用于单板计算所做的工作。
如今，它的产品已嵌入我们的日常生活中，可以在机场的智能家庭设备，医院呼吸机和展示屏幕中找到，仅举几例。SBC在工业设计中也起着越来越重要的作用。现在，工业和嵌入式客户和原始设备制造商使用了超过50％的树莓PI板。
设计工程师选择Raspberry Pi的原因与原始教育受众建立的原因相同：低成本，小型尺寸，巨大的处理能力，易用性以及与各种配件的兼容性。覆盆子PI应用的潜力是巨大的。多年来，它都超出了每个人的期望，并且它的受欢迎程度继续飙升。Raspberry Pi的用途注定要增加几年。
